Error description
Your region goes Short on Storage when acting as a Web Service Requester to an outside vendor to retrieve documents. Storage utilization peeks to 15 times the document size during INVOKE WEBSERVICE COMMAND or first GET CONTAINER after INVOKE WEBSERVICE completes. SOS occurs in EUDSA. Further diagnosis, found that 1)There is no ability at the moment for the pipeline to indicate it no longer requires the SET storage. 2)The other issue is the codepage conversion required of the DFHWS-BODY container. DFHPGCR does not know how big the data will be after conversion. So it acquires a storage area that is guaranteed to be large enough for even the most expansive conversion process. Additional Symptom(s) Search Keyword(s): KIXREVSCB SOS EUDSA DFHWS-BODY PIPELINE DFHSM0133 SM0133

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users * **************************************************************** * PROBLEM DESCRIPTION: Excessive storage usage on EXEC CICS * * INVOKE SERVICE command. * **************************************************************** * RECOMMENDATION: * **************************************************************** An application does an EXEC CICS INVOKE SERVICE command which receives a large response from the service provider. When processing the response, module DFHPIIW issues GET_CONTAINER_SET which results in a large getmain for the storage for the SET. This storage is then unnecessarily retained until end of task. Module DFHPGCR also allocates storage for codepage conversion but this may be more than is necessary. If PI level 2 trace is active then DFHPIIS traces the first 4000 bytes of the DFHREQUEST and DFHRESPONSE containers. To get the data it issues GET_CONTAINER_SET which again may may allocate more storage than required. The combined effect of these issues is to allocate and retain more storage than necessary which can cause CICS to become short of storage in the EUDSA and msgDFHSM0133 may be issued.
Problem conclusion
Modules DFHPGCR and DFHPIIW have been changed to free the SET storage obtained during SOAP processing once it is no longer required. Module DFHPISN has been changed to free the set storage for the work container DFHPARSE-OUTPUT when it is no longer required. DFHPGCR has been changed to allocate and use above the bar storage for codepage conversion of large CHAR containers, when requested by callers. This is used by DFHPISN and DFHPIIW. DFHPIIS has been changed to get container data into a 4k area for trace when required, for request and response containers.
